2

PHYSICAL

Body GrowthChanges in height and weight are rapid in

the first two years of life.Development moves from head to tail


3

PHYSICAL

Brain Development

Brain grows faster than any organ in the body


4

PHYSICAL

Brain is the only organ that can learn


5

PHYSICAL

Brain DevelopmentDuring infancy, neurons form synapses

(networks) very rapidlyStimulation determines which neurons will

survive or die


6

PHYSICAL

Brain Development

Electrical activity increases as brain weight and skull size increase

Cortex begins to specialize as experiences increase


7

PHYSICAL

Brain Development

The two hemispheres begin to specialize – left is more language and right is more visual/spatial storage

Brain is highly plastic or able to be changed during these early years


8

PHYSICAL

Changing states of arousal Infant is awake for short

periods of time

Eventually, wakefulness

increases and a day an night schedule become apparent

Patterns are due to brain development


9

PHYSICAL

Motor DevelopmentFollows head to tail patternNew skills are due to combining simple

skills into more complex actionsCentral nervous system maturation/reflex

inhibitionMovement possibilitiesEnvironmental supportChild’s motivation


10

PHYSICAL

Motor Development

Experience has profound influence

Cultural definition can form environment


11

PHYSICAL

Motor DevelopmentReaching and grasping are perfected in

first year

Pre reaching to Palmar to Pincer


12

PHYSICAL

Learning Capacities Infants become aware of and adapt to their

surroundingsSights, sounds and food can be reinforcers

for learning


13

PHYSICAL

At birth are attracted to novelty


14

PHYSICAL

Newborns imitate the human face


15

PHYSICAL

Perceptual DevelopmentOver first year

Organize sounds into more complex patternsBecome more sensitive to speech soundsNotice units and phrases

of their own language


16

PHYSICAL

Perceptual DevelopmentEye development and visual brain centers

in the first half year lead to:FocusingColor discriminationVisual acuityVisual tracking


17

PHYSICAL

Perceptual DevelopmentDepth perception

Responsiveness to motion thenSensitivity to binocular thenSensitivity to picture cues


18

PHYSICAL

Perceptual DevelopmentContrast sensitivity accounts for visual

preferencesLook at border and single feature thenExplore internal features then

Detect pattern organization thenDiscriminate complex and meaningful patterns


19

PHYSICAL

Perceptual DevelopmentBirth - Size and shape constancy build

understanding of the world of objects Infants - Rely on motion and spatial

arrangements to identify objects6 months – Rely on shape, color and

texture


20

COGNITION

Piaget’s TheorySensorimotor

Circular reaction – Reflexes gradually transformed into more flexible reaction patterns


21

COGNITION

Piaget’s Theory Intentional goal-directed movements


22

COGNITION

Piaget’s TheoryPhysical causality and object permanence


23

COGNITION

Piaget’s TheoryFunctional Play Experimentation


24

COGNITION

Piaget’s TheoryMental representationMake-believe play


25

COGNITION

Piaget – Now We KnowUnderestimated capacities of young infantsNewborns have more built-in equipment to

make sense of their world than Piaget assumed


26

COGNITION

Information Processing – not stagesSensory registerWorking or short term memoryLong term memory


27

COGNITION

Information processing – cont. Information flows Mental strategies operate on it to increase

the efficiency of thinking


28

COGNITION

Information processing – cont.Young Infants

Attend to increasingly more aspects of their environment

Take information more quicklyShift attention from one stimulus to anotherCapable of recognition memoryMemory is sequential


29

COGNITION

Information processing – cont.7 months

Can recall stimuli that are not present2 years

Attention to novelty subsides and sustained attention improves

Can categorize memories and spontaneously sort objects


30

COGNITION

Information processing – cont.End of toddler hood

Excellent recall for people, places and thingsBiology and social experience contribute to

autobiographical memory


31

COGNITION

Social context – VygotskyBy engaging in joint activities with more

skilled partners just ahead of their development (ZONE OF PROXYMAL DEVELOPMENT)

Cognitive competence increases


32

COGNITION

Language developmentHumans have evolved specialized areas in

the brain that support language development


33

COGNITION

Language developmentAs children acquire language, the brain

becomes more specialized for language processing

Complete mastery of some grammatical forms are not achieved until well into middle childhood


34

COGNITION

Language development is assisted through interaction


35

Peek-a-boo teaches turn taking

COGNITION


36

COGNITION

Reflexes will be modified as they are applied to the environment


37

COGNITION

Inhibition/disinhibition


38

COGNITION

Imitation of adult facial expressions and gestures


39

COGNITION

1-4 monthsExploration includes

KickingReachingGrasping

Little anticipation of events


40

COGNITION

1-4 months Awareness of object permanence

Awareness of object solidity Some awareness of gravity and object collision Deferred imitation of adult facial expression –

holds in memory


41

COGNITION

4-8 monthsExploration includes

Improved reaching and graspingSwipingBangingThrowing


42

COGNITION

4-8 months Improved understanding of gravity and

object collisionUse of shape, texture and color to identify

objects as separate units Imitation of adults’ actions on objects –

only after much practice and repetition


43

COGNITION

8-12 monthsGoal directed behavior Improved anticipation of eventsCan retrieve an object from first hidden

locationMore complex behaviors are imitated


44

COGNITION

12-18 monthsExplore objects by acting on them in new

waysTrial and error solutions to sensorimotor

problemsCan search in several locations for a

hidden objectCan imitate behaviors seen 1 week earlier

and in different settings


45

COGNITION

18-24 months Impulsive solutions to sensorimotor

problems due to internal representationCan find an object that has been moved

while out of sight Imitation of entire social roles in make-

believe play


46

EMOTIONAL AND SOCIAL

THEORIESErickson

Warm, responsive care giving necessary Basic Trust versus Mistrust

Guidance and reasonable choices Autonomy versus shame and doubt


47


TheoriesMahler

Sensitive, loving care fosters bonding


48


Provides foundation for separation-individuationRepresentation and language help create a

positive, inner image of motherCan be relied on in her absence


49


Emotional DevelopmentSigns of all basic emotions present in

infancy6-10 weeks = social smileLaughter = 3-4 months


50


Happiness strengthens the parent-child bond

Happiness supports physical and cognitive mastery


51


Emotional Development2nd ½ of first year – anger and fear surface

as stranger anxietySurvival valueMotor improvement


52


Emotional Development8-10 months

Social referencing – ability to understand the feelings of others as perception of facial expressions are organized

Middle of year 2Realize that emotional response of others may

differ from their own


53


Emotional DevelopmentToddler hood

Self-conscious emotions Shame Embarrassment Pride


54


Caregivers help by Relieving distress

Engaging in stimulating play

Discouraging negative emotion


55


Temperament Easy child – (largest group) quickly establishes

routines, is cheerful and adapts easily Difficult child – (10%) Irregular in daily

routines,slow to accept new experiences and tends to react negatively and intensely

Slow to warm up child – (15%) inactive, mild, low-key reactions, negative mood and adjusts slowly to new experiences


56


Biological roots but child rearing can effect change over time

Ethnic and sex differences are due to combined influence of biology and child rearing


57


Development of AttachmentAttachment supports survival

Babies actively contribute to bondingBuilt-in encourage the parent to remain close to

the infant


58


Development of Attachment6-8 months Separation anxiety Use of parent as secure base Indicate true attachment bond has been

formed


59


Development of AttachmentToddlers use language rather than

following and clingingRequestsPersuasion

Develop an internal working model for all future close relationships


60


Deprivation of affectional ties

Lasting social and emotional problemsCaregivers need to adapt to temperament

and physical needs of infant


61


Early in first year develop rich emotional relationships with fathers and siblings

Peer sociability begins in infancy with socially isolated acts


62


Become reciprocal exchanges in the second year


63


Self-development I-SELF

Begins as infant recognizes that his own actions cause objects and people to react in predictable ways

ME-SELF Toddler can see himself as an object of

knowledge and evaluation


64


Self-developmentToddlers compare themselves to others
